Bone mass
Just like the rest of our body, our bones are subject to natural generation,
degradation and aging processes. Bone mass increases rapidly during
childhood and reaches its peak between the age of 30 and 40 years.
With increasing age, our bone mass slightly decreases. A healthy diet
(especially calcium and Vitamin D) and regular exercise help combat this
degradation to a certain extent. By building up muscles you can
additionally increase the stability of your skeleton. Note that this scale
does not show the calcium content of your bones, but it determines the
weight of all bone components (organic and inorganic matter plus water).
Bone mass can hardly be influenced, yet certain factors (weight, height,
age, sex) can lead to slight fluctuations. There are no recognized
guidelines or recommendations available.
